Several Factors Influencing the Efficiency of Bead Mill

1. Grinding bead density and bead hardness


The larger the specific gravity of grinding beads, the greater the impulse, so the higher the grinding efficiency, but the wear of the laboratory bead mill is relatively large, the key lies in the paste viscosity and flow.


2. Particle size and surface finish of abrasive beads


The size of the grinding bead determines the number of contact points between the beads and the material, for the same material, the abrasion rate and the surface of the grinding medium is proportional to the smoothness, so it is also required to smooth the surface of the grinding bead, so as to reduce the abrasion rate. If the grinding bead is not smooth enough, it will lead to the grinding material to crush the grinding bead, the abrasive grinding bead material and material will be mixed in the slurry difficult to separate, this will seriously affect the quality.


3. Influence of cooling water temperature on grinding efficiency


Cooling water is one of the important factors affecting the grinding efficiency of laboratory bead mill, because the grinding medium in the case of high speed and violent operation, mechanical energy into heat, generating a lot of heat. And with the increase of temperature, the materials to be ground will agglutinate, resulting in the quality of finished materials decline. Secondly, the higher the temperature, the longer the life of the laboratory bead mill is also affected.

In addition, the filling rate of the grinding medium and the flow rate of the materials to be ground are also the problems that affect the efficiency and quality. Too fast the velocity of the material to be ground will lead to the product size widening, the pressure and temperature in the grinding chamber is too high, otherwise too slow will lead to low production efficiency.
